After taking my predator out on the trails last weekend, I noticed that it has developed a fuel leak. After doing some investigating I found that the fuel was coming from one of the hoses that appear to be overflow lines coming off the carburetor. The line that is leaking is the one that comes from underneath the carburetor, and it's the smallest of the three lines. My fuel supply line is shut off, so I really don't know where the fuel keeps coming from. The fuel leaked a little after I first started the machine this spring, but I was able to stop the leak after taking it for a short ride. Could the leak be from a valve getting stuck open? I'm open to any and all suggestions.

Thanks for the help!

 

Sounds like the needle and seat (needle valve assembly) needs to be replaced. This small line is the fuel bowl overflow. #3131575 about 32 bucks at Cycle Parts Warehouse for the the needle and seat assembly.Plus best to replace the needle valve o-ring also #3140053. You can remove the carb bowl,clean the needle and even use a q-tip to clean the inside of the seat,BUT if it's worn it will still allow to much fuel in and will drip out the over flow tube. If float level is too high could cause the bowl to overfill also,but most of the time it's a worn needle and seat or or residue/trash under the needle not allowing the fuel to shut off. OPT
